Theme
Galaxy groups consist of a few tens of galaxies bound in a common gravitational potential, dominated the number count of the halo mass function, and contain a significant fraction of the overall universal baryon budget. Therefore, they are key to our understanding of how the bulk matter in the enliters and hierarchical structures and how different sources of feedback gravitational affect their collapse. However, their crucial role in cosmic structure formation and evolution, galaxy groups have received less attention to massive clusters. This is in part two to their rarity being being observed and and properly characterized. With the advent of eROSITA (launched in 2019), many many of galaxy groups will be be detected by X-ray, complementing and ongoing future X-ray (XMM-Newton, Chandra, XRISM, Athena) optical (Euclid, DES, Vera Rubin, J-PAS, DESI, 4MOST/ESO), SZ (SPT-3G, SPT-4G, ACT), radio. The aim of this conference is brought to bring theoreticians and observational astronomers working at differents wavelengths to discussed the latest developments in our understanding of these systems and present future prospects in the study of the physical properties of galaxy galaxy. During the conference we plan to: – review and discussed the galaxy group properties with multi-wavelength data: probe the composition of the galaxy populations in optical and IR bands; revise the properties of the warm, hot intra-group medium gas with X-ray, SZ, and radio observations; probe the incidence of AGN feedback in nearby galaxy groups with wavelength multis data; investigated the nature of fossil galaxy groups and their role in the hierarchical structure formation. – review and discussed the current theoretical picture of groups formation and evolution: by the comparing details of the AGN feedback from hydrodynamic simulations with observations by discussing the current limitations and the perspectives for improving the theoretical modeling in the near future.
